LUNG-TESTER AND TOY.

SPECIFICATION forming part of Letters Patent No. 793,177, dated June 27,1905.

Application filed Janrary 23,1905. $erial No. 242,306.

To /r.// 11 7mm it may concern:

Be it known thatI, HENRY G. UADY, a citizen of the United States,residing at Pine Bluff, in the county of Jefferson and State ofArkansas, have invented certain new and useful Improvements inLung-Testers and Toys, of which the following is a specification.

My invention relates to improvements in a combined lung-tester and toy;and one object of my invention is the provision of a device which willperform the function of testing the lungs and combined with an amusingfeature or toy, the device being extremely simple and inexpensive ofproduction.

Another object of my invention is the provision of a combined toy andlung-tester which will prove a neverending source of amusement andinterest and which will test the lungs and register the power of theexhalation and insure the proper testing of the lungs, as well as makingthe operation a pleasure and delight.

\Vith these objects in view my invention consists of a combinedlung-tester and toy embodying novel features of construction andcombinations of parts substantially as herein disclosed.

Figure I represents a side elevation of the complete device, and Fig. 2represents a vertical central sectional view of the lung-testing toy.

In the drawings the letter A designates a hollow tube or column,preferably made of glass or transparent material and provided on oneside with a scale B, and around the top of this tube is placed a rubbergasket or ringC, and around the lower portion is also placed a gasket orring D. To the upper end of the tube is fitted the cap E, provided witha socket or seat for hoiding the gasket or ring C and provided with asocket or recess F, with which communicates the discharge openings Gr,around which openings are placed a flexible or elastic band H, this bandexerting suflicient pressure or resistance to only permit the escape ofair when pressure from the lungs enters the tube. It will be noted thatthe openings G form discharge or air-exit openings, and the flexible orelastic band H acts as a regulator for the discharge of air through saidopenings, thus providingan air-exit-regulating device. To the lower endof the tube is fitted the sleeve J, provided with a recess K to receivethe lower gasket or ring B and provided with an inlet-opening having ahollow stem L fitting therein, with which communicates the tube M,having the mouthpiece N, in which the air is forced from the lungs inthe operation of testing the lungs. Fitting snugly within the tube isthe float or follower O, to the lower side of which is connected one endof a cord Q, whose lower end is connected at P to the sleeve, and thiscord is preferably made elastic or of spring-wire to exert its tensionagainst the force of air from the lungs. Upon the follower is mounted afigure lt, which may be some fanciful or odd-shaped toy, and in theupper portion of the tube is secured the bell S by means of the rod '1,which is attached at its upper end to the cap.

From the foregoing description, taken in connection with the drawings,the operation of my device will be readily understood, and I wouldsimply state that when desired to use the device air is forced throughthe mouthpiece and impinges against the lower face of the follower,forcing it upward against the tension of the cord or spring andregistering the pressure upon the scale, and when forced to the highestpoint of the column the head of the figure contacts with the bell andsounds an alarm. Thus the device performs the twofold function of a veryamusing and interesting toy as well as a tester and expander for thelungs, and the extreme simplicity and inexpensiveness of the deviceenables it to be used extensively. It will be noted that in normal orinitial position the follower or figure is at the bottom of the tube andis hidden or obscured by the sleeve J; but when air is forced in at Lthe figure is moved up in sight, and this renders the device amusing aswell as useful.

I claim- 1. A combined lung-tester and toy. consisting of a transparentvertical or upright column, an air-exit-regulating device at the upperend of said column, consisting of a cap having a series of openings andan elastic band covering said openings, an air inlet or supply device atthe lower end of the column, a movable follower fitting in said columnand adapted to register the pressure of air from the lungs.

2. A combined lungtester and toy, consisting of a transparent verticalor upright column, an air exit and regulating device carried by saidcolumn, consisting of a cap having a series of openings and an elasticband covering said openings, an air inlet or supply device communicatingwith said column, a follower movable in said column under pressure ofair from the lungs, and an elastic connection connected to the followerfor exerting tension on the follower against the pressure of air.

3. A combined lung-tester and toy, consisting of a transparent verticalor upright column, an air exit and regulating device carried by saidcolumn, consisting of acap having a series of openings and an elasticband covering said openings, an air inlet or supply device communicatingwith said column, a follower carrying a figure and movable in saidcolumn under pressure of air from the lungs, a scale for registering thepressure of air, and an elastic connection secured to the follower forexerting tension on the follower against the tension of air-pressurefrom the lungs and restoring said follower to its normal obscurity.

4. A combined lung-tester and toy consisting of a transparent column, anair-exit-regulating device at the upper end of said column, consistingof a cap having a series of openings and an elastic band covering saidopenings, an air inlet or supply device at the lower end of the column,a movable follower fitting in said column, and an alarm adapted to bestruck by the follower, said follower being normally obscured at thebottom of the column.

In testimony whereof I afiiX my signature in presence of two witnesses.
